Non-Essential Sets for the Dirichlet Problem

Abstract

The 4 b , 4 8 . 5 0 Ti(d, ' 3He)45,47.49S~ reactions have been investigated at an incident energy of 52 MeV. Angular distributions have been measured and spectroscopic factors have been deduced by means of a DWBA analysis. Positive-parity states have been found up to about 9 MeV excitation energy, revealing about 70",, of the Id, proton-hole strength. The 2s, Z , Id3,* and I d , , strength distributions are compared with predictions from phonon-hole coupling calculations.
